These innovative lenses employ Olympus' newly-developed Supersonic Wave Drive? (SWD) technology inside to provide quiet, ultra-fast autofocus (AF) speed, and offer several impressive distinctions, including:
 Olympus 3 new Zuiko lens and 2x teleconvertor Moreover, a new ultra-compact, high-performance ZUIKO DIGITAL EC-20 2x Teleconverter doubles the focal lengths of any lens attached from the wide selection of FourThirds and Olympus E-System lenses, for twice the telephoto power. Now the ZUIKO DIGITAL ED 50-200mm f2.8-3.5 SWD (which covers a zoom range equivalent to 100mm to 400mm on a 35mm camera lens), combined with the EC-20, will provide a huge equivalent zoom range of 200-800mm. "With these three new SWD lenses, we've got outstanding glass to match the high quality performance of our flagship E-3 digital SLR," said John Knaur, senior marketing manager, Digital SLR, Olympus Imaging America Inc. "In testing, the autofocus speed of the 12-60mm has proven to be the fastest in the world, and the 14-35mm is the world's first standard zoom lens to rival fixed focal length lens speed with a bright F2.0 aperture. The fast-focusing 50-200mm telephoto is ideal for sports and action photography, and these three lenses fulfill many of a photographer's focal length needs." All three SWD lenses will be manufactured at the Olympus Tatsuno Plant in Japan, which is equipped with the highest state-of-the-art production technology in the field of optical equipment. Supersonic Wave Drive Technology Olympus-proprietary SWD technology has enabled an ultra-fast, whisper-quiet, high-precision AF system. Two compact, high-powered SWD devices power autofocus at an ultra-high speed by exciting unique elliptical oscillations, while an ultra-compact 5.3mm x 4.3mm optical encoder detects and controls the lens drive position using direct rotation detection without reduction gear. This enables it to achieve a level of precision that's accurate to 5 microns (5/1000 mm). When used in combination with the new E-3, which offers improved AF computation and lens-body communication rates, the SWD motors provide the fastest focusing speed of approximately 170 ms (0.17 seconds). and DE-N3 (+3m-1) |
